제목 A study on the effect of different functional groups on anion exchange membranes  for a Vanadium Redox Flow Battery
초록 Generally cation exchange membranes have used for vanadium redox flow batteries. However, those cation membranes have a severe drawback of vanadium ion cross-over which consequently causes low energy efficiency. To date, many researchers have employed anion exchange membranes to lower vanadium ion cross-over through the membrane by using vanadium ions repulsion principle. In this study, we introduced 3 different vanadium ions repulsing groups as functional group on the anion exchange membranes to investigate the effect on the membrane properties such as vanadium ion cross-over and long term stability. The base membrane was synthesized from vinylbenzyl chloride(VBC) and then cross-linked by divinylbenzene(DVB) within a porous polyethylene(PE) substrate. The prepared membranes were evaluated by physico-chemical properties such as ion exchange capacity, dimensional stability, vanadium ion cross-over and membrane area resistance.
